All I know about the Gap Tech is what I read on the site. Looks to me as if the Smart Top is a little more customizable. Correct me if I am wrong, but on the website it looks as if the Gap Tech defaults to the windows up after the top is raised or lowered. The Smart Top you can program either up or down after either operation. You can also program the sequence to stop or continue if the key is removed during the sequence. The big difference I see is being able to start the sequence with the vehicle in motion, under a selected speed. Functions can be changed either via usb cable or by using top control buttons and radio display. If updates are available, it can be updated via the usb cable. I left the usb cable plugged to the unit mounted behind the subwoofer cover and tucked it behind the smaller cover where the top module was located so I could access it with my laptop if needed. Not sure about price as I did not do any currency conversions. I found a little cheaper price and shipping from some other sources than mods4cars, but not much difference so I ordered directly. I prefer to do this unless savings are substantial in case there is an issue. You made the product, I bought it from you, you make it right. As you said. not saying one is better, this one fit my needs in what I wanted to accomplish. I read about the Gap Tech after this was already ordered, though from what I read, this would have probably still been my choice.
We will be camping Labor Day weekend so no ZFest. I do see you are in GA. I am located approx. 20 miles west of UGA. If you want to see it work and are going to be in the area, send me a message and maybe we could meet. Car is still fairly new to me so I am still learning what is out there for it, though I am pretty much satisfied the way it is.
